74AHC125 74AHCT125 Quad buffer/line driver 3-state Rev. 5 12 June 2020 Product data sheet 1. General description The 74AHC125 74AHCT125 is a quad buffer/line driver with 3-state outputs controlled by the output enable inputs (nOE). A HIGH on nOE causes the outputs to assume a high impedance OFF-state. Inputs are overvoltage tolerant. This feature allows the use of these devices as translators in mixed voltage environments. 2. Features and benefits Wide supply voltage range from 2.0 V to 5.5 V Overvoltage tolerant inputs to 5.5 V High noise immunity CMOS low power dissipation Balanced propagation delays All inputs have a Schmitt-trigger action Input levels: For 74AHC125: CMOS level For 74AHCT125: TTL level ESD protection: HBM JESD22-A114E exceeds 2000 V MM JESD22-A115-A exceeds 200 V CDM JESD22-C101C exceeds 1000 V Latch-up performance exceeds 100 mA per JESD 78 Class II Level A Multiple package options Specified from -40 C to +85 C and from -40 C to +125 C 3.
